Christopher Nolan: 'I never planned a Batman trilogy'

Christopher Nolan has said that he never intended for his film Batman Begins to spawn a trilogy.

The director's third and final installment, The Dark Knight Rises, comes out this summer, and according to Nolan it will be his final Batman film.

Deadline reports that during a recent movie conference Nolan said he had no plan for his sequels, saying: "We never had a specific trajectory. I wanted to put everything into making one great film, I didn't want to hold anything back."

Batman Begins starred Christian Bale, Morgan Freeman and Michael Caine, who are all returning for the final movie, along with newcomers Tom Hardy, Anne Hathaway and Joseph Gordon-Levitt.
